Clitopilus amygdaliformis, a new species from tropical China

Abstract

Clitopilus amygdaliformis is described and illustrated as new from tropical China. It is characterized by its white to chalk white, small to medium-sized basidioma with an eccentric stipe, absence of pleuro- and cheilocystidia, and broadly amygdaliform to limoniform basidiospores with 5-6 prominent longitudinal ridges and a distinct suprahilar depression. It was regarded as C. prunulus, but the latter has a pileus often with somewhat grayish tinge, a central to slightly eccentric stipe, longer and narrower fusiform basidiospores and a temperate habitat.
